We will start our study of BJT amplifiers with the Common Emitter amplifier, commonly abbreviated as the CE amplifier. This configuration is probably the most common of all BJT amplifiers, and the one you will see most often, in one form or another, in the ham literature. Understanding the CE amplifier already gives you a…
Introduction Now that you have the basics needed to understand and analyze transistor circuits, let’s continue our study with the classical textbook configurations of BJT amplifiers. You’ll find these in every course and textbook that deals with amplifiers, though not always with great explanations. The following circuits are textbook circuits, and while you may find … Read more
Introduction Why introduce a new device so soon? We haven’t even learned how to exploit BJTs yet, and already you’re being given even more weird devices! While it is true that most textbooks and course will have you study the BJT in more detail before introducing other semiconductors (and that’s how I first leaned too), … Read more
I’ve noticed that very often, the first active device that students see if they study any kind of electronics past high school is the Op Amp, and only later are they introduced to the humble transistor. From a teaching point of view, I can understand this choice. Op Amps can be treated as a very … Read more
